On the evening of October 27, 2025, 39-year-old Andrew Michael Olson was shot at a home on Pratt Road in the Dayville section of Killingly and later died at Day Kimball Hospital from a single gunshot wound to the chest. Olson had been watching a movie with a 12-year-old boy when the shooting occurred; the child later told investigators that Michelle F. Yeagher entered the room and fired the weapon.

Police located 65-year-old Michelle Yeagher at the scene appearing highly intoxicated. She gave conflicting accounts, at one point saying she acted in self-defense. Investigators recovered a 9mm Smith & Wesson registered to Yeagher; after a medical evaluation she was arrested and faces charges including murder, carrying a dangerous weapon, reckless endangerment, and risk of injury to a child. Bond was set at $1 million and Yeagher is scheduled for a court appearance on December 11. Authorities say there is no ongoing threat to the public while the Eastern District Major Crime Squad continues its investigation.

If anyone knew Olson or saw activity near Pratt Road in Killingly on the night of October 27, what information can be shared with investigators?
